The power generated by an electrical circuit (in watts) as a function of its current c cc (in amperes) is modeled by: p ( c ) = ? 1 2 c 2 + 1 2 0 c p(c)=? 12c 2 +120c

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

How do you determine whether a relationship represented as as graph is linear or nonlinear
